METHOD OF MEASUREMENT OF ANGULAR COORDINATES IN SYSTEMS WITH SUPERSCANNING Russian patent published in 1997 - IPC

FIELD: radiolocation and radio navigation. SUBSTANCE: essence of method lies in increase of measurement precision of angular coordinates of object thanks to additional measurement of time moment t₃ corresponding to failure of signal reflected from target relative to start of antenna scanning for reception and in determination of direction to target for a priori known time laws of antenna scanning with radiation t_rad(θ) and reception t_rec(θ) in agreement with expressions θ_tar =θ_rec(t₃+U_-(x))-θ_o/2,, , where ; θ_rec(t) is function inverse to time law of scanning t_rec(θ) θ_rec(t_rec(θ))=θ;; θ_o is width of antenna radiation pattern by preset threshold levels. EFFECT: increased measurement precision. 4 dwg, 2 tbl
